Humans and possibly a few other primates are the only animals that get a rash from poison ivy. Your dog and cat donât get it, nor do birds, deer, squirrels, snakes and insects. However, be sure to wash your dog after a walk near poison ivy because the urushiol can be carried on dogsâ fur and transferred to you!
Poison ivy, poison oak and poison sumac are plants that contain an irritating, oily sap called urushiol. Urushiol triggers an allergic reaction when it comes into contact with skin, resulting in an itchy rash, which can appear within hours of exposure or up to several days later.he rash that results from the poison plants is a form of allergic contact dermatitis. (Dermatitis is swelling and irritation of the skin.) Skin is not automatically sensitive to urushiol.
